Paypal环境变量凭据

Question

如何为PayPal凭据设置环境变量？我搜了很多遍，但没有任何线索。这是paypal.rb中的代码

PayPal::SDK.load("config/paypal.yml", Rails.env)
PayPal::SDK.logger = Rails.logger
merchant_id = "sts9n"
public_key = "3jnfbc24f76"
private_key = "a0167fd52cf3857e"

Answer 1

可以将凭据添加到credentials.yml中，如下所示

EDITOR=nano rails credentials:edit

在凭据文件中添加PayPal键，如下所示

paypal: 
 development:
  client_id: "sdsdsdvsdvsv"
  client_secret: "sdfsdsdv"
 production:
  client_id: 'sdsdsdvsdvsv'
  client_secret: 'sdsdsdvsdvsv'

然后在配置文件中创建一个名为paypal.yml的YML文件。

development:
  client_id: <%= Rails.application.credentials.paypal[:development][:client_id] %>
  client_secret: <%= Rails.application.credentials.paypal[:development][:client_secret] %>

production:
  client_id: <%= Rails.application.credentials.paypal[:production][:client_id] %>
  client_secret: <%= Rails.application.credentials.paypal[:production][:client_secret] %>
  mode: live

然后在初始化器文件夹中创建一个paypal.rb文件。

paypal_config_file = File.join(Rails.root,'config','paypal.yml')
raise "#{paypal_config_file} is missing!" unless File.exists? paypal_config_file
paypal_config = YAML.load(ERB.new(File.read(Rails.root.join('config','paypal.yml'))).result)[Rails.env].symbolize_keys

CLIENT_ID = paypal_config[:client_id]
CLIENT_SECRET = paypal_config[:client_secret]

这样，在切换到产品开发时，您不需要更改任何代码。

Answer 2

只需将密钥添加到rails凭据：

EDITOR=nano rails credentials:edit

production:
  paypal:
     client_id: 'qwertzuiop'
     client_secret: 'poiuztrewq'

然后在config/paypal.yml中使用此凭据

[…]
production:
  mode: live
  client_id: <%= Rails.application.credentials.dig(:production, paypal, :client_id) %>
  client_secret: <%= Rails.application.credentials.dig(:production, paypal, :client_secret) %>

也可以将环境变量添加到环境配置文件中。例如，在config/environments/production.rb中

PAYPAL_CLIENT_ID = Rails.application.credentials.dig(:production, paypal, :client_id)
PAYPAL_CLIENT_SECRET = Rails.application.credentials.dig(:production, paypal, :client_secret)

在config/paypal.yml中

[…]
production:
  mode: live
  client_id: PAYPAL_CLIENT_ID
  client_secret: PAYPAL_CLIENT_SECRET
